1. What is the simplified form of (–3x^3y^2)(5xy^–1)?
I think it is 15x^4y
2. What is the simplified form of –9m^–2n^5 × 2m^–3n^–6?
I have no idea on this one. :/
3. A rectangular pasture has a fence around the perimeter. The length of the fence is 16x^7 and the width is 48x^4. What is the area of the pasture?

4. What is the simplified form of (3.25 × 10^3)(7.8 × 10^6) written in scientific notation?
2.535 x 10^10 maybe?
5. The size of a certain cell is 2.5 × 10^–9 m. Another cell is 1.5 × 10^3 times larger. How large is the larger cell in scientific notation?
I think 4 x 10^-27
BTW, Please tell me the right anwsers on the ones i missed. I have tried to do this. Thanks!

100% correct. Thanks for helping me double check my answers.
#1
-15x^4y
#2
–9m^–2n^5 × 2m^–3n^–6?
= -18m^-5 n^-1
or
-18/(m^5n)
#3 area = length x width
= (16x^7)(48x^4)
= 768 x^11
#4 correct
#5
2.5 × 10^–9 x 1.5 × 10^3
= 3.75 x 10^-6
Ahhh, Reiny came in. Excellent!

Be careful of these lists of answers without explanations. Sometimes kids deliberately post wrong answers. Sometimes teachers and/or test publishers mix the questions and answer choices up. Sometimes they change them completely!
Be aware!
Do you guys need the choices?
